Yui is the inheritor of a long and intense ninjutsu tradition.
As a kunoichi in training, she studied seduction and sexual skills in addition to infiltration and assassination techniques.
Her family has moved with the times in many ways, so she was not allowed to engage in any “hands on” sexual training until she turned 18.
Her strict and time-consuming training gave her little social time, so she hasn’t had a lot of friends. As a result, she’s noticeably socially awkward despite formal speech and body language training.
